Thanks Bruce!
Going to build one more (for now) and add a pair OTOP12's
From my earlier post about inductors, yourself as well as Bill said I wouldn't need them however the plans call for a limiter... would I get the limiting from a Driverack unit? Or wire the inductor in series (+ or -) to the driver and be done with it. I guess I don't understand the wiring part of Titan subs outside of + to + and - to - Any help here would be greatly appreciated

Yes, you need a limiter. Yes, a driverack will do it. No, the inductor will not. The inductor is for creating a low pass passive crossover. The driverack will take care of the crossover, limiting, EQ, etc.

The limiter is used to keep the voltage from the amplifier exceeding an amount that would create over-excursion of the driver.....which results in buying a new driver.

Be sure and ask any questions about the set up of crossover points, limiting, etc. when you are ready to fire them up. Do NOT try to operate the subs without all of the above in place first......it would be a recipe for disaster.

Will do and thanks again Bruce for your wisdom... Chris, it is the 24" version 3012lf loaded.
This build went well with only minor adjustments (trace lines!) albeit remedied. The second build should go even quicker now that I have made notes on the build sheets! OTOP's will be next with proxied advice on quantity. I'm going to build 4. I'll need to update the plans tho, it's been quite some time ago when I purchased them initially.

Hey guys,
Since my last post on this subject I have built another T39 and used the pair at a receint show with great success! Kick was nice and punchy and for the first time I could hear (and feel) my kick drum!
I am quite pleased with the way these turned out and the cork sniffers had lots of questions during our breaks... tells me they too were impressed!
I gave them the web address so they could have a look around for themselves and build their own as I have done.
The best part is... I can load/unload T39's by myself! What a back saver!

Otop12's are almost completed and will be when the parts I ordered from Leland get here this Friday.
Kudos to Leland! Super nice guy, very helpfull! Couldn't ask for a better retailer...
